Summary of Agreements by Topic

L1 Enhancements for Inter-Cell Beam Management

1. Beam Indication Timing:
• Scenario 2 (Beam indication together with cell switch command) is supported.
• No consensus to support Scenario 3 (Beam indication after cell switch command).
2. Beam Selection for SSB-Based L1-RSRP Measurement:
• Beam selection is performed across L cells from configured or activated cells, with M beams per cell.
• Maximum values of M and L are based on UE capability, with at least M x L = 4 supported.
• Inclusion of current SpCell in the L1 measurement report is configurable.
3. TCI State Activation:
• TCI states in the candidate cell activation/deactivation command are associated with the LTM TCI state pool of the target cell.
• After reception of the LTM cell switch command, UE deactivates all activated TCI states other than the indicated TCI state.
4. Priority Rules for CSI Reports:
• LTM CSI reports are prioritized over legacy CSI reports in case of collision.
5. Beam Application Time:
• Defined as no later than T_LTM-RRC-processing + T_LTM-processing + T_first-RS + T_RS-proc + 3 ms.
6. QCL Type for LTM TCI State:
• DM-RS antenna ports of PDCCH and PDSCH are quasi co-located with reference signals in the provided TCI state with respect to typeA and typeD.
• UE does not expect to be configured with typeA when SSB is configured as a source RS of a LTM TCI state.

Timing Advance (TA) Management

1. TA Acquisition:
• TA acquisition of candidate cells before cell switch command is supported, including for deactivated SCells.
• PRACH for early TA acquisition can be performed on either UL or SUL in the candidate cell.
2. RACH-Based TA Acquisition:
• UE does not detect PDCCH RAR for PRACH transmission triggered for candidate cells.
• After completion of RACH procedure, UE follows the indicated TCI state in the LTM cell switch command.
3. UE-Based TA Estimation:
• UE performs TA estimation if the ltm-UE-MeasuredTA-ID of the candidate cell matches the serving cell.
• UE does not perform TA estimation if the IDs differ.
4. Power Control for PRACH:
• PRACH transmission power is determined by open-loop power control or power ramping configuration.
• UE prioritizes PRACH transmission power allocation over serving cell UL transmissions in case of overlap.

LTM CSI Reporting

1. SpCell Inclusion:
• SpCell measurements are identified in the LTM-CSI-SSB-ResourceSet where the PCI and frequency information match the current SpCell.
2. Collision Handling:
• Priority rules for LTM CSI reports are defined to handle collisions between multiple reports.
3. Semi-Persistent Reporting:
• Activation/deactivation of semi-persistent PUCCH reporting for LTM CSI is clarified.

RACH-Less LTM Procedure

1. TCI State Usage:
• For RACH-less LTM, UE applies the TCI state indicated in the cell switch command until a new TCI state is provided.
2. Beam Indication:
• For RACH-less LTM, beam indication of the target cell is up to UE implementation when followUnifiedTCI-state is not enabled.

General Agreements

1. Specification Maintenance:
• No enhancements are specified for padding bits in L1 measurement reports when the report size is less than 12 bits.
• No consensus to include simultaneousU-TCI-UpdateList under LTM-Candidate-r18.
2. Configuration Parameters:
• Various RRC parameters for LTM configurations are agreed upon, including those for TCI states, pathloss references, and TRS configurations.
3. Processing Rules:
• Processing of an LTM CSI report occupies 1 CPU.
• Accumulation of PUSCH/PUCCH/SRS closed-loop power control for the indicated target cell is reset when the cell switch command takes effect.
